Title: Magnetic recording and reproducing device
Inventor: SHIMOTASHIRO MASAFUMI
IPC: G11B5/02
Filed: 1983-05-04
Abstract: PURPOSE:To improve the quality of the audio signal by multiplexing frequencies of a video signal and a code-modulated audio signal and using a high-frequency bias magnetic field to record them on the same track and separating the frequency of the encoded audio signal to demodulate it at a reproducing time. CONSTITUTION:Though a luminance signal and a chrominance signal are subjected to normal signal processings and are recorded and reproduced, the audio signal is recorded on a video track, and tracks and heads only for sounds are required. The audio signal is processed digitally and is reproduced without being affected by the noise, the amplitude variance, and the nonlinear distortion which are generated in electromagnetic conversion systems of a rotary head 21 and a magnetic tape 22. Further, since the high-frequency bias magnetic field is applied to record the signal, the higher harmonic distortion is restrained to a low level. Thus, the cross modulation signal level for the input of said three signals can be lowered to a level where the picture degradation is not caused while holding S/N of the signal of a normal VTR.

Title: Change gear control device for continuously variable transmission
Inventor: MORI HARUHITO
IPC: F16H61/02
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To decelerate the speed independently of the car speed without giving the uncomfortable feeling to a request of a driver at the time of switching change gear ratio from a D range to any one of the two ranges by setting a change gear ratio of the two ranges so as to have a constant ratio in relation to the change gear ratio of the D range before switching the change gear ratio. SOLUTION: In a control system of the change gear control device for a continuously variable transmission, throttle open degree TVO, engine speed Ne, the number of revolution of input shaft Nt, the number of revolution of output shaft No, and the gear change signal are input to a CVT control unit. Change ratio of the number of revolution of input shaft when the speed is changed from a D range to any one of two ranges by a driver is set a value close to a constant value. During the traveling at a speed in the D range, when the driver changes speed to any one of the two ranged, in the case where change ratio of the change gear ratio is remarkably different in response to the car speed, engine brake feeling to be obtained in the traveling condition becomes different large.  Generation of a large difference in the engine brake feeling is eliminated by setting a change ratio of the gear change ratio independently of the car speed.

Filed: 1994-03-10
Abstract: PURPOSE:To improve safety at the time of internal short circuit by taking out respective electrodes, wherein the positive or negative electrode of a battery element is electrically divided into plural, to outside of a battery vessel by respective leads to electrically connect the electrodes via resistors having PTC effects respectively. CONSTITUTION:Electrodes, wherein a positive or negative electrode is electrically divided into (n) (n>2), e.g. positive electrodes 22-2n, are taken out to the positive electrode outside terminals 81-8n of a battery can 4 by electrode leads 71-7n to be connected. Current, generated in negative electrodes 12-1n in and the positive electrodes 22-2n, flows into a point A when internal short circuit occurs in the point A by electrically connecting these respective terminals to each other via resistors having PTC effects. However, this current is cut by the PTC resistor of a path via the leads 72-7n and 71, and current generated by the negative and positive electrodes 11 and 12 becomes most of the short circuit current in the point A. Consequently, the temperature in the point A can be prevented to become as high as to cause thermal runaway even in a battery having large (n), that is, large capacity, to improve safety.

The case 2' is pressed by a spring 3', yet the body 6 lowers furthermore because of the larger force of the pressing head, and the glass 20 is press-formed. When the head rises after finishing the forming, a solenoid valve 15 receives a signal, pressurized air flows to apply the pressing force to the case 2' through the spring 3', and the pressing die 1 separates from the glass 20. The case 2' rises similarly together with the body 6 through a cover 10, and the formed glass 20 remains on the die 12. When the pressing head reaches the rising end, the pressurized air is exhausted from a muffler 19.
